CLOCK-FRAME.

Patented Oct. 1,1912,

Application led September 29, 1909. Serial N o. 529,134.

Richmond, in the county of Henrico and.

- State of Virginia, have invented new and useful Improvements in Clock-Frames,- of which the following is a specification.

This invention relates to improvements in clock trames and more particularly.' to a to provide means whereby the main spring may be removed therefrom without impairing the usefulness of any of the parts of the clock, 'and it consists in thenovel arrange.- ment of parts hereinafter full set forth. The invention has for its object to provide acheapn and. simple means whereby main springs maybe quickly removed from clock mechanism withoutnecessitating the operation of Vremoving the frame, while at the same time provides the arbor carrying the main gear wheel 'and the spring with firm and reliable bearings'.`

which will be more apparent as thedescrip l tion progresses the. invention'resides in the novel construction and arrangenieii-'taofparts# hereinafter fully described and claimed.'v

'In the accompanying drawing, Figure 1 .is a rear elevation of a part ofa clock frame constructed-in accordance with the present' invention. Fig. :2 is a longitudinal-sectional view upon the line2-2 of Fig. -l1. Fig. 3 is a detail view, partly in section illustrating the spring yengaging post of the frame. Fig. 4 is a fragmentary perspective vieys7 of the inner convolution of the springend a portion of the spindle.

AIn the accompanying drawing Ithe ynuwith a .suitable opening 4 which is in linef with n. larger opening 5 provided 1n crossfV` bar 2^ o'f the rear plate of the frame. Both of these openings 4 and. 5 are adapted'ffor:

clock frame so constructed and arranged as With the above, and other objects in view;

meral 1 designates the front plate off-,the

the reception of thereduced-extensions ot a winding spindle 6. The opening 4 is adapt ed to receive the reduced end Ga of the Windingarbor 6, while the opening 5 is considerably larger than the arbor topormit the ready removal of said arbor. Thls v gear 7 has rotatably mounted thereon a suitable'ratchet wheel 8 scuiedto the spindle through the medium of a removable pin 9,

ratchet wheel. The spindle 6 is provided with 'the usual oset or hook 10 which is ,adapted to connect with the usual hole l1 provided in the inner end of the winding or operating spring 12. The spring 12, in the rily retained in its woundv position through the medium of a suitable ring 13, of that class commonly employedlby clock makers,

convolution bent uponL itself to provide an ,eye 14 whereby it is connected with a lower `threaded post 15 provided upon the frame. This post 15, as clearly illustrated in Fig. 3 of the Vdrawing has screw threads 16 on one end of its and which is adapted for the reception of a securing nut 17 anda binding nut 18. The opposite end of the reception of a nut 19, whereby the said post not only retains the end of the spring 12, but also effectively retains the lower portions of the frame plates 1 and 2 in proper spaced relation with each other.

The cross bar-2", is provided with threaded an etfec-tiveas well as a removabley caring therefor. The rectangular plate 20 is reelements-23 which lare adapted to adjacent the ends of the plate 20 and to engage threaded openings 24. within the face plate 2.

vwhich extends through'the hub 8a of said' present instance is adapted to be tempora- `post is also-threaded and is adapted .for the openings 24 which receive the screws 23' reduced extension of the spindle 6 to rovide movably connected to the face plate 2 of the frame through the medium of threaded ref f tainin pass t rough suitable openings providedk y From .the above description, taken in con-.1

and the said spring has" its out-ei' end or COPY neotion with the accompanying drawing, itL

16, so that thil post may he withdrawn from the eye '14 of the spring l2. The spindle 6 is then forced through the enlarged opening 5 and the .Caf :iig .is well as the gear 7 may be removed on; the trame, it being understood that the inner convolution of the Spring will readily yield so as to allow the hooi; l0 to be withdrawn from the hole 11 of the said spring. lt will be further noted that the boss 21 of the plate 20 is of a thickness corresponding with that of the thickness ot the cross bar i. so that the shoulders of the spindle will he provided with a firm bearing and .so ihat an)7 ordinary spindle may he employed. and ity will he also noted that by proriding` the post l5 with the threads lt' it will he unnece'fssainvv to entirely Withdraw the ysaid posi, from the frame so that the post will not he displaced and ma)v he readilyv inserted within the eye il mi' the spring when lhe said spring is repositioned upon thtl frame.

llaving thusA fully deff'frihed thel invention what is claimed as new i ln ronihinatimxa pair of' clock frame pluies having side har- @zal ero f bars inte` gral with said bars and located inwardly of the ends ofsaid side bars, Said cross bars having alining openings, one of said cross bar openings being larger than the other, posts securing the plates together, one of said posts being adapted to en age the eye of a main spring and being ormed with screw threads and slidable through one of. the frame plates, nuts threaded on said screw threads and against the sides of said plate and adapted to permit the removal of said screw-threaded posts from one or both of said plates, a plate removably securedA to one of the cross bars of said frame plates and having a boss snugly fitted in the larger cross bar opening, a winding arbor having reduced ends engaging the boss and the opening in the opposite cross bar, a main gear Wheel and a ratchet Wheel rotatable on said gear wheel and'mounted on said arbor, said ratchet Wheel having a hub, and a in extending through said hub into the ar or and removably connecting the main gear and ratchet wheels to said arbor, said arbor being removable through the larger cross bar openinfr.

ln testimony whereof I allix my signature in presence of vtwo witnesses.
